Kenya’s October weather outlook is in.
Above-average rainfall is expected across most of the country, with an increased risk of flooding, landslides and localised infrastructure damage in some areas.

[Hewa App @HewaApp]

With the enhanced rainfall, there is an increased risk of:
• Flash and riverine flooding in low-lying areas and river basins
• Landslides in steep highland areas
• Urban flooding where drainage is poor
• Some rural roads becoming difficult or impassable

It’s official, the 2026 El Niño has broken a record for the highest ocean anomaly in 170+ years… Incredibly reaching that threshold a full 2 months ahead of 2015’s record of +3.02C set on Nov 18th.
See that red line? That’s 2026.
Every other bold line are the strongest El Niño’s on record.
2026 is in a league of its own.

We have two months left for this El Niño to continue to intensify. And it will.
